The SPREAD allows different Fixtures in the same Shape to operate out of
phase with each other. That is, they are all doing the same function, but you
can allow them to perform the Shape out of step with each other.
The Coarse Spread defines how many different positions a Fixture can be in
during one repetition of the Shape Cycle. If the Fine Spread is set to zero,
the Fixtures will always be evenly spaced within the Shape Cycle.
Eg. If the Coarse Spread is 2, there are two different points in the Cycle that
a Fixture can be at. Fixture 1 leads, and Fixture 2 trails half a Cycle behind it.
Fixtures 3, 5, 7 etc will have the same position as Fixture 1; Fixtures 4, 6 etc
will have the same values as Fixture 2.
If the Coarse Spread is 4, Fixture 1 will lead the Shape, and Fixtures 2 to 4
will all trail at different points behind it in the Shape Cycle, equally spaced.
Fixture 5 will be at the same point as Fixture 1, Fixture 6 will be at the same
point as Fixture 2, and so on.
It is obviously not possible to have a Coarse Spread value greater than the
number of Fixtures in the Shape, because when the two figures are the
same, all the Fixtures are at different points in the Cycle, evenly distributed
through it. This is called an EVEN Spread.
The Fine Spread value is in degrees, and is an offset which allows the
distribution around the Shape Cycle to become uneven. Using the Fine
Spread enables you to vary this offset. High values cause the Fixtures to
become bunched close together on the Shape Cycle.
10.3.1 To EDIT a Shape
In order to Edit a Shape, it must be in the Programmer.
Once you press CLEAR, a Shape is lost, unless you have stored it in a
Memory. (See Section 10.4 Recording a Shape in a Memory).
If you have applied different Shapes to the same set of Attributes of the
same Fixtures, you will only find the latest Shape in the Programmer. But if
you have applied, for example, a Circle move to Selected Fixtures, then a
Tilt Saw move onto the same Selected Fixtures, both Shapes will be in the
Programmer. This is because the Tilt Saw only controls the Tilt Attribute –
the Pan is still controlled by the Circle.
Similarly the same Circle applied separately to two different groups of
Fixtures will appear as two different Shapes.
All the Edits made to a Shape apply to all the Fixtures in that Shape.
You can use the LOCATE FIXTURE function from within the Shape
Generator. See section 4.7.1 LOCATE FIXTURE.
• Turn the Key to Program. Puts you in LIVE PROGRAM MODE menu.
• Press Softbutton G [SHAPE GENERATOR]. Puts you in SHAPE
GENERATOR menu.
• Press Softbutton B [EDIT A SHAPE]. Softbuttons display all the different
Shapes currently in the Programmer.
• Select the required Shape for Editing using the Softbuttons.
Softbuttons F and G allow you to move forwards and backwards on the
different pages of Shapes.
